SAMUEL E. PURDUM. OF MACOMB, ILLINOIS.

VENDING MACHIIQ'E.

Application filed May 25, 1925-.

1 all whom it may concern.-

lde it known that I, SAMUEL E. PUnnUM, a citizen of the United States, residing at lliacomb, in the county of McDonough and State of lllinois, have invented a new and useful V ending Machine, of which the following is a specification.

This invention relates to a check-control device especially designed for use in connection with. vending machines, the primary object of the invention being to provide a device of this character of a novel construction to insure against a coin other than the coin designated to operate the machine, operating the locking mechanism.

Another object of the invention is to provide a device of this character which when operated, will act to throw the coin into a coin receptacle supported thereunder.

A. further object of the invention is to provide a sliding actuating member having its inner extremity bent upwardly and forwardly to constitute an ejector for throwing the article vended, from the machine.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.

teferring to the drawing:

Figure 1 is a front elevational View of a vending machine equipped with a coin-con trol device constructed in accordance with the invention.

Figure 2 is a horizontal sectional View through the upper portion of the checkcontrol device.

Figure 3 is a vertical sectional view through the device, illustrating the position of the ejector when it has been moved to eject an article.

Figure 4 is a vertical sectional view through the device illustrating the position taken by the locking arm when a counterfeit coin has been inserted in the machine.

Figure 5 is a sectional view through the device illustrating the position of the locking arm when engaged. by a coin of the proper size.

Serial No. 82,800.

Figure 6 is a sectional View taken on line 66 of Figure 2.

Figure 7 is a sectional view taken on line 77 of Figure 2.

Figure 8 is a sectional view taken on line 88 of Figure 2.

Referring to the drawings in detail, the reference character indicates the cabinet of a vending machine equipped with a check controlled device constructed in accordance with the invention, the cabinet in the present illustration comprising a plurality of vertical compartments in which articles are positioned.

The check-control device forming the essence of the present invention embodies a base plate 6 which is formed with an elongated cut out portion 7 formed with a circular end portion 8 that has a notch 9 formed in the wall thereof.

In the formation of the elongated out out portion ears are "formed at a point substantially intermediate the ends thereof, the ears being indicated at 10 and provide bearings for the pin 11 that supports the looking arm 12 to be hereinafter more fully described. Slidably mounted on the plate 6 is a combined check receiving plate and ejector indicated at 13 which has one ofits ends extended upwardly at 14 presenting a finger piece to be gripped by the operator to move the plate 13 in actuating the checkcontrol device.

As shown by Figure 3 of the drawings, the opposite end of the sliding plate 13 is bent upwardly and forwardly, the extreme end thereof being bent downwardly at 15 providing an ejecting flange to engage the ar ticles held in the compartments of the machine to force them from the machine.

Formed in the check receiving plate 13 is an elongated cut out portion 16 provided. with a central coin receiving opening 17, the elongated out out portion 16 being pro vided to allow the locking arm 12 to move upwardly through the coin receiving plate 13 when it has been actuated by a check or coin of the proper size.

Adjacent to one end of the elongated cut out portion 16 is a relatively small cut out portion 18 defining a locking shoulder 19 to to be engaged by the shoulder 20 formed at the inner extremity of the locking arm 1:2, and it will be seen that the length of the locking arm 12 is such that if a coin such as indicated at 9% as shown by Figure 4, is positioned in the coin receiving opening 17, and the coin isv not of the proper: sizeito engage the locking arm 12 at the proper time, the shoulder 20 Will engage the shoulder 19, locking the plate 13"against rearward movement, or to a position-where.

it may be brought forwardly to eject an article from the machine-.-.

At the forward end of the locking arm 12. is a shoulder 21 whiclris adapted to en gage the shoulder 22 of the plate-l3cwhen the plate 13 is movedforwardly, thereby restricting forward movement. of the plate 13 after it hasbeen-moved'toeject anart-iele from the machine.

The forward vunderse'dge or the-arm 12 is inclined as at-23 so thiatrwhenga coinrsuch as indicated at2at and illustrated by Figure of the drawings, is: positienedwithin the openin 's- 17 of the plate 13, the" C0111 may ride over this inclinedsnrface, swinging the forward end upwardly and moving the shoulder from a locked position :as shown by Flgure 4; of thedrawing to an unlocked position a's'slrown by- Figure 5, allowing the tion of-the. spring engaging: the locking arm 12'to normally arrgevthev inner end of the locking. arm 12 upwardlyi Thusflt will be seen thatwhe-nwamoin has been inserted: and: has moved to actuate the arm 112, .the spring. 251s: placed nnden tension to -theu-end'that:

when the coin has moved .to'ia: positionzwith 111' the openings =17, d1rectly. over the; opening 8, the coin" will be forced a through: the: plates 13 and 6 and dropped-into awcoin receptacle positioned thereunder.

In the" formation of! the device;- the: plate;

6 has portions thereof stamped therefrom,

the portions being: indicated 'ate26y'a ndibent ose 1.42

upwardly to provide guides for the plate 13. CtlttOlltlaPOl'tlOIlSQ?"211 6 also provided adjacent tothehedges ofthe plates 6 and accommodate the tongues 28 of the table 29 supported thereabove to secure the table 29 to the plate.

The-table 29 includes inwardly extended flanges 30 that overlie the plate 13 and preventntheplate from moving upwardly when the coin carried thereby engages the under edge 23 of the arm 12. This table receives articles that drop from the article compart ments: oftl'ie machiine so. that they maybe engaged by the men-aher15 and thrown from the machine.

As before stated when a coin of the proper size is positioned in thezmachine, the coin.

will engage under the forward end of the loclringarm 12moving-it to aposition as shown by FigureF) of the drawing, but if a coin of too small a diameter is positioned in the openingl'i, the shoulder 20 will remain behind the shoulder 19 owing to the fact that the shouldersav-ill be in cooperative relation with each other prior to the engagement of the coin with the forward end of the arm 12.

In view of the foregoing detail description, it'is believed that a further: detail description as to the ope-*atiouof the device is unnecessary.

I claim In a check-control device, a base plate, anejector plate slida-bly mounted on the base plate and having a coin receiving opening, a-loclring arm pivotally supported under'the base plate, the'ends of said arm adaptedto engage'the. ejector plate to restrict movementv thereof, and said locking arm adapted.- to be moved to'its inactive position by acoincarried by the ejector plate.-

In' testimony that 'I. claim the foregoing as-11iiy-own, IEhave' hereto atlicred my signatu-re.

SAMUEL R. PURDUM.
